I asked about this before I started recommending Humaxes (I help out with local dissability issues) and was advised not to connect
them to local networks as they could present security hazards. (As could the random connection of TV's/bluray players etc)
These issues seem to be completely ignored.
I did ask online somewhere if there was firewall support (cant remember if I asked here or elsewhere)
My point is - I'm seconding the request for firewall - ideally everything blocked until an IP address AND port AND protocol is specifically allowed.
ARP, most UDP and other protocols should also be dissabled. Personally I'd like to see all IPV6 blocked permanently.
Anyway - Whatever the details it would be nice if someone could look into it.
